Patent JP-H0956057-A (JP)
Title: Protective device for constant-current circuit
Inventor: MURAJI TETSURO
IPC: H02H3/00
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To prevent the application of a voltage higher than the maximum rating of a driven load across the driven load by connecting a Zener diode having a breakdown voltage lower than the maximum rating of the load in parallel with the load. SOLUTION: When the voltage applied across the load 1 is lower than the breakdown voltage of a Zener diode 6, a constant current is supplied to the load 1 by controlling the applied voltage Vy so that a voltage Vx can become constant. When the resistance of the load 1 abnormally becomes higher, the voltage Vz applied across the diode 6 becomes higher than the breakdown voltage of the diode 6 and a large current flows to the diode 6. Then the voltage Vx becomes higher and a constant-current drive driver 3 lowers the applied voltage Vy upon receiving an H-level signal from a comparator 4. Therefore, the application of a higher voltage than the breakdown voltage of the diode 6 across the load 1 is eliminated and the application of a higher voltage than the maximum rating of the load 1 is prevented.

Filed: 1988-09-13
Abstract: PURPOSE:To accurately measure an electric energy in the manner of eliminating the effect of an offset voltage by feeding back the output signal of a bridge switch to an intergation circuit after dividing the voltage to a half. CONSTITUTION:A load voltage is detected by an auxiliary transformer 1 and a consumption current is detected by an auxiliary current transformer 3, and the product of both amounts is calculated by a time-division multiplying circuit 5 for a pulse-width modulation, then plus and minus voltage signals eop, eon corresponding to the electric power are outputted and supplied to the bridge switch 11 of a voltage-frequency conversion circuit 7.

Title: Tire for iced and snowy road
Inventor: HIRAYAMA SEIICHI
IPC: C08K5/00
Filed: 1988-09-13
Abstract: PURPOSE:To obtain excellent drive and brake-ability and wear and abrasion resistance by providing a tread surface with a surface layer section composed of rubber composition in which water soluble particles and or vulcanized rubber particles of low adhesive property to tread rubber are compounded. CONSTITUTION:A tread surface is provided with a surface layer section composed of rubber composition in which water soluble particles and or vulcanized rubber particles of low adhesive property to tread rubber are compounded. The surface layer section touching a road surface is formed with fine porosities, due to the elusion of the above mentioned water soluble particles or the dropout of vulcanized rubber particles of low adhesive property, by which the friction coefficient of a tire, the friction coefficient on an iced road surface in particular, is increased resulting in the display of the excellent drive and brake-ability of the tire on an iced and snowy road surface. In addition, since the tire surface touching the road surface changes itself to be porous but not to the interior, the lowering of wear and abrasion resistance due to the lowering of the hardness of the surface layer section can be regulated or prevented.

Title: Carrier acclimatization operation
Inventor: SUMINO TATSUO
IPC: C02F3/34
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To perform the acclimatization of a carrier in a short time in a nitrification equipment and also to efficiently perform the carrier acclimatization even when the flow rate of waste water is low, or in the presence of active sludge. SOLUTION: In this operation, the ammonia nitrogen load on a carrier is maintained at a >=30 mg-N/L carrier/hr level. When the initial flow rate of waste water is lower than the design flow rate, as in a new sewage treatment plant, waste water is stored in a storage vessel and then, the waste water is intermittently supplied from the storage vessel to a nitrification vessel through a denitrification vessel to increase the waste water flow rate and also, the waste water is subjected to intermittent aeration, i.e., aerated only at the time of supplying the waste water by an aeration device, to maintain the ammonia nitrogen load at a >=30 mg-N/L-carrier/hr level.  Further, at the time of using a nitrification equipment in which active sludge is suspended in the nitrification vessel, at least any one of the operation of (intermittent water supply)/(intermittent aeration) and an operation of setting the aerobic solid matter residence time (ASRT) of activated sludge to an ASRT value of the activated sludge, such that no nitrifying bacteria are retained in the activated sludge, is performed to maintain the ammonia nitrogen load on the carrier at a >=30 mg-N/L-carrier/hr level.

Title: Integrating process of metal-metal capacity
Inventor: DONALD C DENNIS
IPC: H01L21/02
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To locate a capacity at any level in an integrated structure by allowing the part of a first electrode to overlap a second electrode for forming a common region and then allowing the first electrode to extend across the common region to connect a capacity to a previous level outside the common region. SOLUTION: An upper electrode 18 is separated from the other sections of an integrated circuit 12 by spaces 28 and 30. On the other hand, a lower electrode 14 is extended over the entire region of the integrated circuit 12. The lower electrode 14 and at least part of the upper electrode 18 overlap with each other to form a capacity region 10a or common region, and thereby a capacitance is not directly connected to a prior level of the integrated circuit 12. For example, a capacitance 10 is located outside the capacitance region 10a and is connected to a prior level by means of a window in contact with the lower electrode 14. With this structure, there is no need for forming a capacitance in the window and the likelihood of a voltage drop problem caused by a step coverage generated accompanying when the capacity is formed in the window can be reduced.
